Converting between ounces (oz) and kilograms (kg) is a common task, especially in cooking, shipping, and international trade. Here's how to do it:
The key to converting between ounces and kilograms is knowing the conversion factor:
To convert ounces to kilograms, multiply the number of ounces by the conversion factor 0.0283495.
Formula:
Example: Convert 1 ounce to kilograms
Therefore, 1 ounce is equal to approximately 0.0283495 kilograms.
To convert kilograms to ounces, multiply the number of kilograms by the conversion factor 35.274.
Formula:
Example: Convert 1 kilogram to ounces
Therefore, 1 kilogram is equal to approximately 35.274 ounces.
Here's a summarized, step-by-step process:
The ounce has a long history, dating back to ancient Rome. There are different types of ounces (e.g., avoirdupois, troy, fluid), but for mass, we generally refer to the avoirdupois ounce, which is defined as exactly 28.349523125 grams. The kilogram, on the other hand, is the base unit of mass in the metric system, which is widely used around the world. The kilogram was originally defined as the mass of 1 liter of water.
The Importance of Standard Units:
Having standard units of measurement is crucial for trade, science, and engineering. The establishment and maintenance of these standards are managed by organizations like the International Bureau of Weights and Measures (https://www.bipm.org/).
Here are some common scenarios where you might convert between ounces and kilograms:
Shipping: When sending packages internationally, shipping companies often use kilograms for weight, while you might know the weight of items in ounces.
Cooking: Many recipes, especially in the US, use ounces for ingredients, while others (or nutritional information) might use grams or kilograms.
Purchasing Goods: When purchasing goods internationally in bulk, the weight is often denoted in Kilograms instead of Ounces.
See below section for step by step unit conversion with formulas and explanations. Please refer to the table below for a list of all the Kilograms to other unit conversions.
The ounce (symbol: oz) is a unit of mass in the imperial and United States customary systems of measurement. It's commonly used for measuring weight, but it's essential to distinguish between weight and mass. Mass refers to the amount of matter in an object, while weight is the force exerted on that mass by gravity.
There are different types of ounces, the most common being the avoirdupois ounce and the troy ounce.
Avoirdupois Ounce: Used for everyday measurements of food, household items, and other general goods.
Troy Ounce: Primarily used for measuring precious metals like gold, silver, and platinum.
It is important to note that one pound of troy is lighter than one pound of avoirdupois since there are less ounces to make it. One troy pound = 373.24 grams and One pound of avoirdupois is equal to approximately 453.592 grams.
The term "ounce" has ancient roots, derived from the Roman term "uncia," which meant one-twelfth. This referred to one-twelfth of a Roman pound (libra). Over time, this unit evolved and was adopted into various measurement systems across Europe.
While no specific law or person is directly tied to the "ounce" itself, its historical significance is linked to commerce, trade, and the standardization of weights and measures. Standardized measurement played a crucial role in the development of science.

Kilogram (kg) is the base unit of mass in the International System of Units (SI). It is a fundamental unit used to measure the amount of matter in an object. Unlike units like length or time, the kilogram's definition has historically been tied to a physical artifact.
For over a century, the kilogram was defined by the International Prototype Kilogram (IPK), a platinum-iridium cylinder stored at the International Bureau of Weights and Measures (BIPM) in France. This meant that the mass of every kilogram in the world was traceable back to this single object.
The IPK was not a perfect standard. Over time, it was observed to have changed mass slightly compared to its official copies. This instability, however small, was a major concern for scientific measurements that require utmost precision.
On May 20, 2019, the kilogram was redefined based on fundamental constants of nature. The new definition is linked to the Planck constant (), a cornerstone of quantum mechanics. The Planck constant has a fixed numerical value when expressed in SI units:
By fixing the value of , scientists can realize the kilogram through experiments involving quantum phenomena. This change provides a far more stable and reproducible definition than relying on a physical object. The experiment that is commonly used to realize the kilogram based on Planck's constant is called a Kibble balance.
It's important to distinguish between mass and weight. Mass (measured in kilograms) is the amount of matter in an object, while weight is the force exerted on that object due to gravity. Weight is measured in Newtons (N). The relationship between mass and weight is:
